The complete Shimano Ultegra Di2 drivetrain offers smooth and swift electronic shifting with a stiff and efficient 50/34T crankset. Coming with a Shimano WH-RS500 wheelset, this lightweight carbon machine is race-ready. Designed for total aerodynamic performance, the Carbon 60TON frame and fork combination delivers the perfect balance of stiffness, comfort, and weight-savings. Stacked with technological gains to make this carbon road bike a fast and efficient racing machine, the podium beckons for those who ride the Cento1 Air Road Bike.
To build a great monocoque carbon frame, Wilier looked for the perfect balance of stiffness, comfort and responsiveness at the lightest possible weight. Carbon fibre is an ideal material for bicycle frames because of its qualities of elasticity, capacity to withstand stresses, and its strength-to-weight ratio. The higher the modulus, the stiffer the composite. On the other end of the spectrum, the lower the modulus, the more elastic it will be.
In the construction of this bike they implemented MR60H for stiffness in the critical stress areas where lateral stiffness equates to greater efficiency. Then used T800H and T700SC, with more elastic characteristics, to ensure comfort and sure-footed handling. Each was used as minimally as possible once our demanding strength and durability standards were met, ensuring the lightest weight frame possible.
Thanks to the solid central BB386 EVO movement, Wilier designed generous rear seatstays and, in keeping with the long-held Wilier Triestina tradition, they are asymmetric. Concept symbol of the Cento1, the asymmetric rear stays improve pedalling efficiency against the torque generated by the chain.
The brake and derailleur cables flow inside the frame. This allows the frame to be aerodynamic, protect and cover the cables.
The fork is the first part of the frame to hit wind resistance. This is where Wilier began in their revolution of the Cento1; they posed a relatively simple question, which required an incredibly sophisticated answer. How do you replicate the aerodynamic efficiency of the TwinBlade’s fork, but in a conventional fork? Using the rigidity already developed in the Cento1SR’s integrated fork shape (a 14% increase in torsional rigidity in comparison with Cento1, thanks to the repositioning of the down and horizontal tubes in relation to the headtube), Wilier created 2 small channels below the fork’s crown, in line with the TwinFork concept in the TwinBlade.
These two small channels aid airflow, while enabling increased rigidity. The downtube, in its new lowered position, integrates seamlessly with the fork crown while generating another air foil which is capable of reducing wind resistance even more. The fork’s brake entry hole is hidden by the downtube, which keeps it clean and well protected.
A Wilier design and Ritchey production in carbon monocoque. Wilier designed it to integrate seamlessly with the sophisticated aerodynamics of the frame. The locking mechanism is combined. Simple yet intelligent at the same time, the aero remains incredibly secure. There are two fastening systems which work together simultaneously. The first, internal part, locks the saddle to the frame. The second, a clamp, locks the saddle in place by preventing it from slipping into the saddle tube.
In developing the TwinBlade Wilier learned that if the rear oblique seatstays are kept as low as possible, the aerodynamics of the frame are improved. This is what they have done also with the Cento1AIR, moving the stays as low as possible, within UCI standards. The rear brake is entirely covered by the stays. As with many other frame parts, the vertical stays have also been designed according to the Kamm theory. A clean cut, creating a virtual "fin" from an aerodynamic point of view, but which still allows them to remain light and within UCI rules. Compared to other solutions, the rear brake installs to the frame in a standard way, with a normal socket wrench, without requiring additional parts.
The cable system has been further enhanced by routing the cables inside the frame's tubes. The Integrated Plate Adjuster is a special device which allows for the fastening and adjusting of cables. Integrated Plate Adjuster seamlessly integrates with the frame, thereby bestowing a very clean look where no elements are exposed to air resistance. Easily interchangeable to be compatible with different electronic group sets, the Integrated Plate Adjuster allows one to route cables inside the tubes and to redirect them towards the bottom bracket. Combined with the special cable guide plate located under the bottom bracket, Integrated Plate Adjuster keeps cables neatly spaced from the downtube’s inside surface. Noise and shifting efficiency loss can occur when a cable does not maintain its position.
The dropout evolves and implements its name. The 3D Dropout is born. It is not a mere rear derailleur mounting plate anymore. The dropout now extends over a third dimension and serves also as a cable stop. This newly acquired third dimension leads to an especially stiff dropout compared to conventional fastening plates. Thanks to its generous size, Wilier created two holes (a larger one for the mechanic group set cable and a smaller one for the electronic cable) to route cable housing or cables without compromising the stiffness of the dropout. In this manner, the dropout may be used both for mechanical and electronic group sets.
For the mechanical group set, it allows one to use a shorter cable housing sleeve and to have the shifter cable follow its natural curve since the rear derailleur cable is located closer to the fastening point. This improves shifting efficiency and smoothness. The exit routing is not the only improvement. The cable stop has been positioned above the drive-side chainstay, thereby keeping the cable flawlessly suspended within the stay. The internal cable routing through the down tube is kept at a distance from the frame’s inner surface to assure that there is no friction during shifting. The wiring exit point of the electronic group set has also been optimised as it is setback and above the drive-side dropout. This feature facilitates and expedites rear wheel removal and installation.

Wilier was born in 1906 thanks to the brilliant idea of a trader from Bassano, Pietro Dal Molin, of building bicycles on his own account. His forge or "Steel horses" rose as a small workshop along the banks of the river Brenta, at Bassano del Grappa, and it became more and more successful by keeping up with the increasing demand for bicycles.
The size chart below will get you on the right size bike. Experienced riders may also wish to refer to the geometry chart for more detail.
Getting the Right Fit
At Wiggle we measure each of our bikes to build accurate size charts for our customers. Our qualified team of mechanics then individually check each order, against measurements supplied by you, to ensure the size chosen is correct. Another reason you can have complete confidence when buying a bike from Wiggle!
If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
